exhaust manifold design is CAR specific, 1NZ_FE engine is in Corolla, Corolla Axio, Fielder & Yaris - Vitz. Now you need to do some home work measure the 3 lengths
- a. length between collar & bend of manifold,
- b. distance between the firewall & collar
- c. width between firewall & manifold bolts. - [ jahan manifold nai tight hona hai gaskit ki sath ]- note down by making a figure on paper.
Go back to engine dealer without accusing of anything ask him to show you all available 1NZ-FE & 2NZ-FE engines check the exhaust manifolds measure the items mentioned, which ever has smaller bends & short collar to bend lenth, ask him to remove & give to you for experiment.
or least take the pictures from 3 different angles of items at yard & share so that swap expert can guide you to make right selection of manifold to avoid disaster.
